Coventry Chaser

• Rugged - simple construction for reliability and long life.
• Compactness - permitting use on machines with limited clearance.
• Accurate Pitch - due to the guiding action of the non-cutting portion of the die.
• Adjustability - providing fine regulation of finished diameter for 3a class threads.
• Clean and smooth threads - as the dies have cutting angles suited to the material being used.
• RH and LH thread - by only changing chasers.
• Parallel threads - due to the very efficient support of the dies in the Die head.
• Minimum downtime - for change of thread size, important for production economy on short to medium batch runs.

Coventry chasers are designed so that cutting takes place at the chamfer and the first full tooth. The other teeth are above centre height, so they act as a nut, ensuring accurate pitch.

• Precision ground threads.
• Lip types to suit various materials.
• Four standard chamfer angles: 15, 20, 33 and 45 degrees.
